Roller mill knowledge -- lubricating oil and ＂life span＂

When roller mill is used to grind powder, the parts of roller mill bearing should be added with regular and quantitative grease. In the operation of roller mill, there is not only friction between material and spindle, but also friction resistance at the joint of components. The main function of lubricant is to reduce friction resistance between components. If the lubricating oil is insufficient, the friction degree of the spindle will be increased, so that the temperature rises too high, which will lead to thermal deformation. In this case, in combination with a lot of practice, found that the use of oil and gas lubricating oil bearing temperature rise, than when using the oil mist lubrication to reduce 5-8 ℃, grease lubrication reduce 9-16 ℃. As the value increases, the cooling effect becomes more pronounced. Oil and gas lubrication technology has been effectively applied to roller mill spindle at ultra-high speed and achieved good results. Ultrafine Raymond mill also belongs to a kind of roller mill powder machine, with large difference between ordinary Raymond mill grinding fineness has great distinction, and its applicable range is very wide, common, such as kaolin, limestone, coal, stone and calcite, barite, iron oxide red, iron oxide green, aluminum hydroxide, pigment, bentonite, etc., can use superfine Raymond mill for superfine powder processing.

 

After understanding the importance of lubricants to Raymond timo, let's look at the factors that affect the service life of roller mill.

 

The reasons that affect the lifespan of roller mill are as follows: 1. Due to improper installation or poor material, large and small blades often fall off or break during the operation of the separator. When small blades fall off or break, the fineness of finished products becomes coarse. This situation should be shut down for processing, the small blade can be updated. 2. As the lining plate of the inner sleeve of roller mill is subject to the impact of materials for a long time, the lining plate is easy to wear. If it is not replaced in time, the inner sleeve will wear into holes. It can be seen that there are mainly two factors determining the service life of roller mill powder machine. The first factor is the quality of roller mill powder manufacturing process and the second factor is the quality of installation process. As the damage of roller mill powder machine affects the economic loss caused by production, the installation quality is particularly important, and even determines the service life of roller mill powder machine.
